Families In DR Congo queued alongside little coffins, mourning the children and others killed in a rocket strike allegedly launched by M-23 rebels.
Relatives held up crosses with the names of the deceased. They reserved their harshest comments for Rwanda, the country just over the border that they, their government, and the United Nations allege is supporting the M23 terrorists - an accusation disputed Rwanda has continuously refuted.
On May 3, at least five rockets struck displaced people's camps in Goma, killing largely children and women.

On Wednesday, 22 children were buried, many in half-size or smaller caskets, together with the bodies of 13 other fatalities.
"My daughter-in-law was murdered in the Mugunga camp," said Fikiri Mvano at the mass funeral at a cemetery in Kibati, north of the city.
"She was the victim of bombs dropped by Rwanda in support of the M23... She left us her children. She had nine, and three died with her."
Rwanda has denied any involvement in the attack, claiming it is being exploited as a scapegoat and implying.
Congo and the United States have said that the assaults were fired from Rwandan and M23-controlled areas.
The two-year fight, M23's longest offensive since a 2012-2013 insurgency in which they took Goma, has driven tens of thousands to evacuate their homes in an area that has had little respite since Rwanda and Uganda invaded over three decades ago.
In recent months, conflict has returned to Goma, a large lakeside metropolis of approximately two million people.
